The party to a lease (賃貸借) who lets the other party use a thing, such as land or a building, in return for rent; in everyday words, the landlord (Civil Code, Article 601). The lessee (賃借人) may not transfer the lease, or sublet the thing, without the lessor's consent, and where the lessee lets a third party use it without that consent, the lessor may cancel the contract (Article 612).
